Software
The software for the DM6 Holey S looks very similar to the DM2 Supreme software. The first page, "Mouse Macros," doesn't contain the macro function, but CPI adjustment (six color-coded levels, 200–16,000 CPI, increments of 50 CPI) and button remapping (including keyboard, media, macro, and shortcut functions). The second page, "Settings," then includes the macro editor, basic Windows pointer settings, and LOD adjustment (L/M/H). All setting changes are saved to the on-board memory, so the software does not need to be running (or be installed) all the time. On my system, the software had a RAM footprint of 55 MB on average when running in the foreground, which doesn't change when minimized, be it to the taskbar or the system tray. Upon exiting the application, all processes are terminated, as they should be.
Lighting
The DM6 Holey S has but a single RGB lighting zone, which is a singular LED below the right main button. It can be turned on or off with a button at the bottom of the mouse.
Here's a short demonstration video of the RGB lighting:
